Sodium weights 0.968 so the density is equal to 968
Answer:
none
Explanation:
Newton's first law says an object in motion will stay in motion at the same speed and direction unless acted upon by some force.
No force is necessary for the object to keep its speed and direction on a frictionless surface.
A typical barometer measures the pressure of the location at where you're at. Once it displays the pressure, you can determine the height using the hydrostatic pressure. The equation is written below:
P = ρgh,
where
ρ is the density of air
g is the acceleration due to gravity
h is the height
Therefore, if the pressure increases, then the height also increases.
They are called Ions
Definition is this: atom of molecule with a net electric charge caused by the loss or gain of one or more electrons.
Hope this helps! :D
